What is MOST likely to decrease a subordinate's effectiveness according to TSgt Niland's comments?

A misunderstanding of a fair and impartial trial is likely to decrease a subordinate's effectiveness because it can lead to a lack of trust in the system and the processes that govern their work environment. When individuals do not fully comprehend what constitutes a fair and impartial trial, they may feel uncertain about the justice and fairness of the evaluations and decisions that affect them. This sense of uncertainty can contribute to decreased morale, increased anxiety about their standing within the organization, and a belief that they are not being treated equitably.

As a result, their motivation and productivity can suffer, leading to a negative impact on their overall effectiveness. By fostering a clear understanding of what a fair and impartial trial entails, leaders can help ensure that subordinates feel secure and supported in their roles, which can bolster their performance and commitment to the mission.
